So after years of my HR215 running like a dream, I've had a bunch of issues this season and I'm out of ideas on how to fix them. Essentially what happens is it cold starts fine, and runs well at full speed for a while. After 10 or so minutes of cutting I notice the engine bogging down a bit when I hit heavier grass, but pausing for a second lets the revs come back up. After about 20 minutes, the engine starts bogging down even during light cutting to the point where it'll eventually stall. Once it stalls, it will start again under full choke, but as soon as I take the choke off it'll die again. If I leave it until the next day it'll repeat the cycle all over again.

Mower has new spark plug, cleaned the carb, new air filter.

Any ideas on what might be causing this or what I need to tune up / change in order to get it to stop?

Hello mRyanAB,

Sounds like you are having a fuel starvation issue according to your description.

Take the fuel line off at the tank and see how well the fuel flows. I have seen a few different models that actually had a pencil style tapered fuel filter in the tank line nipple, or it is hiding inside the fuel line.

The tank may have to be removed for a good cleaning, then replace the fuel line. If it does have the tiny filter I mentioned, take it out and install an inline compact style or pancake style fuel filter.
